WILLIAM T. DE WORTH, OF BORDENTOWN, NEW JERSEY.

.HOSE-COUPLING.

To all whom it 'may concern:

Be it known that I, VILLIAM T. Dr. IVORTH, a citizen of the UnitedStates, residing at Bordentownl` in the county of Burlington and Stateof New Jersey, have invented a new and useful Hose-Coupling, of whichthe following is a specification. i

This invention relates to couplings and is more particularly adapted foruse in connecting hose such as used in apparatus utilizing compressedair, steam, etc., as motive power.

The object of the invention is to provide a simple andA durable couplingwhich is inexpensive in construction and can be easily put together ordisconnected.

A still further. object is to provide a coupling which can not be,easily broken, is capable of resisting heavy tortional strains,

and which is perfectly rigid at all times.

With the above and other objects in view the invention consists ofcertain novel features of construction and combinations of parts whichwill be hereinafter more fully described and pointed out in the claim.

. In the accompanying drawing, which is a. section through the coupling,I have shown the preferred form of the invention.

' Referring to the -drawing by characters of reference, A and B are thetwo members of the coupling the member A being provided with a tubularcylindrical portion l having an annular shoulder 2 provided with screwthreads 3 .engaged by a nut 4. Extending from the shouldered end. of thecylindrical portion l is a tapered tubular extension 5 the bore of whichconstitutes a continuation of the bore within the cylindrical portion l.rIhe member B 'has a gradually tapered bore 6 corresponding with thetaper of the extension 5 and an annular flange 7 is formed lat vone endof this member B. The large end of the bore 6 is preferably slidablyflared as at 8 to correspond with a small enlargement 9 formed at thelarge end of the eXtension 5.

The cylindrical portion l is adapted to be suitably secured to onesection of a hose while the member B is adapted to be secured to theother section thereof. When it is desired to couple the hose sectionsthe member B is forced longitudinally. upon the eXtension 5 and theenlargement 9 becomes seated within the flared end i8 of the bore 6. iThe.

' specification of Letters Patent.

Application led. September 7, 1906.

two portions are thus held together by frictional contact and can not beforced apart.

unless unusual pressure -is exerted upon them. dien it is desiredto'uncouple the members the nut d is rotated by means of any suitabletool and bears against the flange 7 and exerts a longitudinal androt-ary pressure thereagainst suiiicient to force the two members apart.It will be seen that a coupling' of this nature is very simple inconstruct-ion in that it is formed of but three parts and is capable ofresisting severe strains both tortional and longitudinal.

The preferred form of the invention has been set forth in the foregoingdescription but I do not limit myself thereto as I am aware thatmodifications may be made therein without departing from the spirit orsacriiicing the advantages thereof, and y -l therefore reserve the rightto make such changes as fairly fall within the yscope of the claim.

That is claimed is:

A coupling comprising a tubular member having an intermediate externallythreaded annular shoulder extending around the entire circumferencethereof and provided with a smooth continuous'interior bore of the samecross sectional diameter throughout its entire length, thez exteriorwalls of said member on one side of the shoulder being tapered towardsthe adjacent end of the member, vand the exterior walls of the member onthe opposite side of the shoulder being of uniform thickness and adaptedto engage a tube to be coupled, a correspond- 1 ingly internally taperedtubular member arranged to receive the tapered portion; of the firstmentioned Vmember and to frictionally engage the same throughout itslength, said receiving member having a circumferential flange upon oneend thereof and adapted to bear against the project beyond the annularshoulder, and a nut engaging the threads upon the shoulder and disposedto bear against the flange to shift the receiving member longitudinally.

In testimony that I claim the foregoing` as my own, I have heretoaffixed my signature in the presence of two witnesses.
